I need a little help. Can anyone identify this flintlock pistol? Is it real or a replica? I found it in my grandfather's garage in a box of hunting items. It appears that someone started to sand the wood stock in order to refinish it. It says Made in Spain, has the word Vendi or Mendi stamped into the barrel, the serial number 17027 in two spots and 12 M/M next to the serial number. Any help would be greatly appreciated.
